Troll in the long term

[tz-announce] 2014b release of tz code and data available
by Paul Eggert March 25, 2014

March 25, 2014

The 2014b release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting near-future time stamps Crimea switches to Moscow time on 2014-03-30 at 02:00 local time. (Thanks to Alexander Krivenyshev.) Move its zone.tab entry from UA to RU. New entry for Troll station, Antarctica. (Thanks to Paul-Inge Flakstad and Bengt-Inge Larsson.) This is currently an approximation; a better version will require the zic and localtime fixes mentioned below, and the plan is to wait for a while until at least the zic fixes propagate. Changes affecting code 'zic' and 'localtime' no longer reject locations needing four transitions per year for the forseeable future. (Thanks to Andrew Main (Zefram).) Also, 'zic' avoids some unlikely failures due to integer overflow. Changes affecting build procedure 'make check' now detects Rule lines defined but never used. The NZAQ rules, an instance of this problem, have been removed. Changes affecting commentary and documentation Fix Tuesday/Thursday typo in description of time in Israel. (Thanks to Bert Katz via Pavel Kharitonov and Mike Frysinger.) Microsoft Windows 8.1 doesn't support tz database names. (Thanks to Donald MacQueen.) Instead, the Microsoft Windows Store app library supports them. Add comments about Johnston Island time in the 1960s. (Thanks to Lyle McElhaney.) Morocco's 2014 DST start will be as predicted. (Thanks to Sebastien Willemijns.) Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2014b.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2014b.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2014b.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2014b.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

Macao vs Macau in tzdata2014a/iso3166.tab
by Tomas Klacko March 23, 2014

March 23, 2014

Hi, the tzdata2014a/iso3166.tab lists "MO Macau". It used to be "MO Macao", for instance in tzdata2013d. Looking at: http://www.iso.org/iso/home/standards/country_codes/updates_on_iso_3166.htm it shows "MO Macao" (via the OBP link on page 14). I would like to check, is the "MO Macau" entry in tzdata2014a/iso3166.tab correct? Thank you, Tomas

Time zone in Troll station
by Bengt-Inge Larsson March 21, 2014

March 21, 2014

Hello IANA! I have noticed that a number of research stations in Antarctica are listed in the tz database, but none in the UTC-1 to UTC+1 range, even if there should be such stations. One such station is the Troll station, which is operated year-around and belongs to Norway. I had a mail conversation with the responsible authority, the Norwegian Polar Institute, about which time zone the Troll station actually uses. The Troll station station officially uses UTC+0. During the dark season March-October, when no air or overland travel is done, it uses Norwegian summertime UTC+2 to simplify communication. So I suggest you add a new zone called Antarctica/Troll You may confirm this through Paul-Inge Flakstad at the Norwegian Polar Institute ( flakstad(a)npolar.no ) Yours Sincerely Bengt-Inge Larsson Sweden From: Paul-Inge Flakstad Sent: Monday, February 03, 2014 12:49 PM To: Bengt-Inge Larsson Cc: Nettredaktør Subject: RE: Time zone in Troll station Hi again Bengt-Inge, I can now confirm that Troll is indeed at UTC/GMT 0. Furthermore - should it be of interest to you - our overwintering team follow Norwegian time (including summer time) during the period they are alone at Troll (March-October). This practice is in place simply to make communication with the head office in Norway more convenient. Thank you for asking us about this. Questions like this and feedback in general are important factors in identifying weak spots in our information channels. In this case, we will update our website with more correct information about the Troll station. Best regards, Paul-Inge Flakstad From: Paul-Inge Flakstad Sent: 3. februar 2014 11:04 To: 'Bengt-Inge Larsson' Cc: Nettredaktør Subject: RE: Time zone in Troll station Hi again Bengt, I see now that my initial reply might have been misleading. Our website page about Troll (where I pulled the info from) states that "Troll is 2 hours after Norwegian time". With Norway in GMT +1, this would implicitly place Troll in GMT -1. However, I believe this is wrong, and that you are correct; Several reliable(ish) sources place Troll in GMT 0, and I assume they base this on geographical coordinates. This also fits nicely into the "2 hours behind"-info on our website, provided one is comparing to Norwegian summer time. I have sent an e-mail to our Antarctica department, asking for verification, and will come back to you with a definite answer as soon as I receive their reply.

And some other source, unchecked reliability, says there is Greenwich Time in the Troll area. Or is it ? Bengt-Inge Larsson From: Paul-Inge Flakstad Sent: Wednesday, January 29, 2014 10:34 PM To: Nettredaktør ; Bengt-Inge Larsson Subject: SV: Time zone in Troll station Hi Bengt, Troll is 2 hours behind Norwegian time.

Which time zone is kept at the Troll research station in Antarctica (what are the clocks there set at)? Or what is the time difference to Norway ?

google translator gone mad - translates ukrainian word 'bes' ("without") as 's' ("with") (i tried both translating into polish and eglish, both translations are opposite to what was in orginal). The decree from june 1990 do not mentions previous zone - just states that country moves to zone +2 GMT without addition of one hour (without DST) ie +2 GMT. with best regards Bogdan Krusiński

Ukraine 1990
by Bogdan Krusiński March 16, 2014

March 16, 2014

Hello, the contenst of decree at http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html contain only one point: "1. Установити з 1 липня 1990 року на території Української РСР час другого часового поясу без додання однієї години." "1. Intorduction from 1st of July 1990 on territory of Ukrainian SSR time of two hours without addition of one hour". I'm a bit disturbed because I was directed by astro.com to these archives where it is translated as: "Set on 1 July 1990 in the Ukrainian SSR, the second time zone with the addition of one hour." "without" is not "with". Pozdrawiam serdecznie Bogdan Krusiński http://www.astrologia.pl

While doing research on atomic bomb testing, I found that at one point, when JI was being used for that testing, the time being used was not Hawaiian time but rather the same time being used on the ships, which had a GMT offset of -11 hours. This apparently applied to at least the time from Operation Newsreel (Hardtack I/Teak shot, 1968-8-1) to the last Operation Fishbowl shot (Tightrope, 1962-11-4). The document that lead us to that conclusion is by Herman Hoerlin, "The United States High-Altitude Test Experience: A Review Emphasizing the Impact on the Environment", Los Alamos LA-6405, Oct 1976. Fas.org/sgo/othergov/doe/lanl/docs1/00322994.pdf. See the table on page 4 where he lists GMT and local times for the tests; a footnote for the JI tests reads that local time is "JI time = Hawaii Time Minus One Hour". A little give-back for the use of your database in informing the atomic test tables on Wikipedia. Thanks. Lyle McElhaney Lmc(a)ashabon.com

Windows 8.1 and tz data?
by Donald MacQueen March 11, 2014

March 11, 2014

In the email announcement titled " 2014a release of tz code and data available", there is this statement: Microsoft Windows 8.1 and later support tz database names. I did not see this mentioned on the tz list and an hour's googling brings me no joy. Does anyone have any links that will ease my confusion?

by Paul Eggert March 9, 2014

March 9, 2014

The 2014a release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting near-future time stamps Turkey begins DST on 2014-03-31, not 03-30. (Thanks to Faruk Pasin for the heads-up, and to Tim Parenti for simplifying the update.) Changes affecting past time stamps Fiji ended DST on 2014-01-19 at 02:00, not the previously-scheduled 03:00. (Thanks to Steffen Thorsen.) Ukraine switched from Moscow to Eastern European time on 1990-07-01 (not 1992-01-01), and observed DST during the entire next winter. (Thanks to Vladimir in Moscow via Alois Treindl.) In 1988 Israel observed DST from 04-10 to 09-04, not 04-09 to 09-03. (Thanks to Avigdor Finkelstein.) Changes affecting code An uninitialized-storage bug in 'localtime' has been fixed. (Thanks to Logan Chien.) Changes affecting the build procedure The settings for 'make check_web' now default to Ubuntu 13.10.

No Virgin Islands Data
by Hank W. March 8, 2014

March 8, 2014

The data for the Virgin Islands, both British & US, is missing. I checked an old dataset (2012j) and found them at the end of the northamerica file. They have since been replaced by a note saying 'see southamerica', but they're not in the southamerica file, either. Hank W., Austin, Texas, USA

Possible error in Europe/Kiev for 1991 - 1992
by Alois Treindl March 8, 2014

March 8, 2014

In western and Ukrainian astrology circles, there is on ongoing dispute about which timezone was in force in Kiev/Ukraine on the date the parliament decided about its independence, on 24 August 1991. Mostly, a timezone of GMT +3h is considered correct. This is in conflict with what TZ database states for that date. TZ database holds: # Most of Ukraine since 1970 has been like Kiev. Zone Europe/Kiev 2:02:04 - LMT 1880 2:02:04 - KMT 1924 May 2 # KievMTime 2:00 - EET 1930 Jun 21 3:00 - MSK 1941 Sep 20 1:00 C-Eur CE%sT 1943 Nov 6 3:00 Russia MSK/MSD 1990 3:00 - MSK 1990 Jul 1 2:00 2:00 - EET 1992 2:00 E-Eur EE%sT 1995 2:00 EU EE%sT Which makes reference to these DST rules #DST rules for Russia after WW2 Rule Russia 1981 1984 - Apr 1 0:00 1:00 S Rule Russia 1981 1983 - Oct 1 0:00 0 - Rule Russia 1984 1991 - Sep lastSun 2:00s 0 - Rule Russia 1985 1991 - Mar lastSun 2:00s 1:00 S Rule Russia 1992 only - Mar lastSat 23:00 1:00 S Rule Russia 1992 only - Sep lastSat 23:00 0 - Rule Russia 1993 2010 - Mar lastSun 2:00s 1:00 S Rule Russia 1993 1995 - Sep lastSun 2:00s 0 - Rule Russia 1996 2010 - Oct lastSun 2:00s 0 - #Modern EU rules Rule EU 1981 max - Mar lastSun 1:00u 1:00 S Rule EU 1996 max - Oct lastSun 1:00u 0 - # E-Eur differs from EU only in that E-Eur switches at midnight local time.

Via my US colleage David Cochrane, I received copies from a Moscow fellow, first name Vladimir, who reported several government documents, refering to Ukrainia timezones. Vladimir writes: --- quote Good news that now we have more documents online in Ukrainian language as well as Google translator. > why this decree states to go off DST when DST was not observed in Kiev in 1991. I did a research in laws and now we have an answer. Unfortunately, we should change a little our DST tables for Kiev and Ukraine. First in Ukraine they changed Time zone from UTC+3 to UTC+2 with DST: 03 25 1990 02:00 -03.00 1 Time Zone 3 with DST 07 01 1990 02:00 -02.00 1 Time Zone 2 with DST * Ukrainian Government's Resolution of 18.06.1990, No. 134. http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html They did not end DST in September, 1990 (according to the law, "summer time" was still in action): 09 30 1990 03:00 -02.00 1 Time Zone 2 with DST * Ukrainian Government's Resolution of 21.09.1990, No. 272. http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html Again no change in March, 1991 ("summer time" in action): 03 31 1991 02:00 -02.00 1 Time Zone 2 with DST DST ended in September 1991 ("summer time" ended): 09 29 1991 03:00 -02.00 0 Time Zone 2, no DST * Ukrainian Government's Resolution of 25.09.1991, No. 225. http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm This is an answer. Since 1992 they had normal DST procedure: 03 29 1992 02:00 -02.00 1 DST started 09 27 1992 03:00 -02.00 0 DST ended * Ukrainian Government's Resolution of 20.03.1992, No. 139. http://www.uazakon.com/documents/date_8u/pg_grcasa.htm ------ end quote I (Alois) interpret him like this: - On 1 Jan 1990, Kiev was on GMT + 3h (I call this 3he, 3 hours east). - on 25 March 1990, at 02:00 am, it went to DST, i.e. to 4he - on 1 July 1990, at 2:00 am, it shifted the standard time, kept the DST, moving effectively from 4he to 3he - no change on 30 Sept 1990, the kept DST, i.e. stayed on 3he (Russia ended DST on that data) - no change on 31 March 1991, Kiev stayed on 3he (Russia began DST on that data) - on 29 Sept 1991, at 03:00 am, Kiev ended DST, went to 2he - on 29 March 1992, 2:00 am, Kiev started DST, went to 3he - on 27 Sept 1992, 2:00 am, Kiev ended DST, went to 2he I have used Google translation to get the content of the links Vladimir provides: A) http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html " Set on 1 July 1990 in the Ukrainian SSR, the second time zone with the addition of one hour." This page says that Ukraine adopted 2he as standard time on 1 July 1990. One could interpret this that it talks about the timezone being 2he plus one hour. But I do not think it does. I think it means: Standard time moved to 2he, the clock was shifted west by one hour, i.e. one hour was added in the course of transition. (from h3e to h2e, if DST was not in force, or from h4e to h3e, if DST was in force). The statement does not confirm whether DST was in force or not at that data. B) http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html states that on 30 Sept 1990, Ukraine did not turn clocks back, but continues to use DST. This implies that DST was indeed in force, at that time. C) http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm states that on 29 September 1991, DST was ended and clocks set back by one hour. My conclusion is: TZ database missed the onset of DST in March 1990, and in consequence, missed its end in September 1991. The goverment document C) clearly states that DST ended in Ukraine on 29 Sept 1991, a date when TZ database says that DTS was not in force. I propose this correction of Europe/Kiev Zone Europe/Kiev 2:02:04 - LMT 1880 2:02:04 - KMT 1924 May 2 # KievMTime 2:00 - EET 1930 Jun 21 3:00 - MSK 1941 Sep 20 1:00 C-Eur CE%sT 1943 Nov 6 3:00 Russia MSK/MSD 1990 Jul 1 2:00 2:00 1:00 EET 1991 Sep 29 3:00 2:00 E-Eur EE%sT 1995 2:00 EU EE%sT

Wrong entry for Israel tz information
by AvigdorFin March 8, 2014

March 8, 2014

Greetings, It seems we found an error in Israel DST transition for the year 1988. Please check if I'm right and correct me it I'm wrong. This is the current information for the year, the transition has happened according to this on Friday night, changing to Saturday. $ zdump -v Israel | grep 1988 Israel Fri Apr 8 21:59:59 1988 UTC = Fri Apr 8 23:59:59 1988 IST isdst=0 gmtoff=7200 Israel Fri Apr 8 22:00:00 1988 UTC = Sat Apr 9 01:00:00 1988 IDT isdst=1 gmtoff=10800 Israel Fri Sep 2 20:59:59 1988 UTC = Fri Sep 2 23:59:59 1988 IDT isdst=1 gmtoff=10800 Israel Fri Sep 2 21:00:00 1988 UTC = Fri Sep 2 23:00:00 1988 IST isdst=0 gmtoff=7200 I check the Parliament ( Knesset ) records and there it's stated that the transition should take place on Saturday night, when the Sabbath ends and changes to Sunday. The definition in the source file is as follows: Rule Zion 1988 only - Apr 9 0:00 1:00 D Rule Zion 1988 only - Sep 3 0:00 0 S Which result with the times above. When changing the source to be: Rule Zion 1988 only - Apr 10 0:00 1:00 D Rule Zion 1988 only - Sep 4 0:00 0 S And compiling it with zic we get $ zdump -v Israel | grep 1988 Israel Sat Apr 9 21:59:59 1988 UTC = Sat Apr 9 23:59:59 1988 IST isdst=0 gmtoff=7200 Israel Sat Apr 9 22:00:00 1988 UTC = Sun Apr 10 01:00:00 1988 IDT isdst=1 gmtoff=10800 Israel Sat Sep 3 20:59:59 1988 UTC = Sat Sep 3 23:59:59 1988 IDT isdst=1 gmtoff=10800 Israel Sat Sep 3 21:00:00 1988 UTC = Sat Sep 3 23:00:00 1988 IST isdst=0 gmtoff=7200 And the transition is as decided by the parliament on Saturday night toward Sunday. I also added the following lines to the source file Link Asia/Jerusalem Israel Link Asia/Jerusalem IST-2IDT Please check me out and if I'm right, correct the next release of the tzdata file. I don't know how many people and organizations are still interested in data from 1988, but the record should be set right.

West Virginia broadcasters 1946 DST proposal
by Garrett Wollman March 8, 2014

March 8, 2014

Quoting from /Broadcasting * Telecasting/ of March 18, 1946: In a move believed to be unprecedented in radio, the newly-formed West Virginia Broadcasting Assn., comprising all stations in the state, will adopt daylight savings time form April 28 through Sept. 29 -- although West Virginia clocks will remain on standard time throughout that period. The time change was unanimously voted by the broadcasters at a meeting held in Charleston March 9. Representatives of all of the state's 14 stations agreed to the resolution. On March 12, all stations included the resolution in all newscasts. Under the plan, radio clocks will be changed to conform to network clocks [ed: the networks observed New York City time, which had DST in 1946] when time change occurs. This means that, unless the West Virginia legislature takes action to the contrary during a special session to be held in two weeks, West Virginians will have two time schedules -- that decreed by the state an that observed by radio. Time Announcements Participating stations will give time-announcements by the radio clock; they will make no rate adjustments, since their proposition is based on the assumption that West Virginia timekeepers are out of step with radio -- not vice versa. The article goes on to quote the full text of the resolution. -GAWollman
